The stop block sits in front of the rail basically, but I am confused by your rail holders, mine look different. Anyway, you should be able to push the rail nearly to the edge. The front needs a bit of space for the belt holder.
/edit: Oh, wait. It’s a LR3… Sorry. You can still push it a bit closer, but not enough I guess. 
Well, I’ll sleep on it for now and tomorrow I will probably just cut pipes to correct length…
I’ve cut the pipes.
I started preparing SKR PRO 1.2 I’ve bought.
Can I power it up with just power supply connected to it? No steppers or anything? Can I put flash card and power up from 24v - and not from usb?
Yes, you can power the board with no steppers or endstop attached. What you cannot ever do is plug or unplug the cables in while the board is powered. That’s a recipe for blowing up stepper drivers or the controller itself.
Yes, you can power the system from 24V and flash firmware or interact with the display.
Thank you, MakerJim!
Board flashed correctly. TFT works fine. I plan to connect all together tomorrow, but I’m not sure if I will be able to do anything with it, because my printer do not want to work correctly and I don’t have tool mount or even housing for board and screen…
Let’s see if I can print anything today…
Yay! I think I have managed to get my printer to work correctly again!
Full maintenance done and it looks like it works again. Hopefully tomorrow morning I will have housing for SKR. Keep your fingers crossed!
hi everyone! belts on, finishing wiring steppers and endstops, but one question:
in the docs it says “z1: jumpers stay in place”, but on all photos jumpers are changed in every single stepper controller. so what should it be?
also in that table about wiring skr pro 1.2 for LR3 it has 7 entries and board has only 6 places for stepper controllers. what’s going on?
can you post photo of your skr board wired correctly?
However I don’t understand why axes move only through menu and physical button (is it called encoder?) but when I switch to touch screen move commands stay unanswered completely. Do I need to flash TFT35 as well?
I solved axes not moving in touch screen mode problem - changing baud rate of connection fixed that.
I just noticed I added this thread in wrong category. Can someone move it to LowRider builds category, please?
Updated. I didn’t even know I could do that. 
LOL, now I checked and I could have done that myself! Thanks, though!
LowRider has hit me with it’s belt holder today! This machine is aggressive! (if the operator has no idea what they’re doing) 
I had to reprint base for Y belt tensioner
Oh, and now I understand why people like those joggers so much…
Preparing to cut the crown in the plywood as a test, but…
I noticed that sometimes while rolling on the rail machine hits rail blocks. It rolls further after little hit, but why can that be? Why it hits rail blocks?
That should not happen. 
I had this happen once when i had bold heads and nylock nuts on the wrong sides (inserted bolts wrong way)
Is this normal that when I unplug machine Z axis goes down? I understand that stepper is not trying to support it anymore, but does one expect this behavior? Also it goes down only on one side for me…
